ABSTRACT

Development of high-quality 2D hexagonal boron nitride (hBN) layers and boron nitride nanotubes (BNNT) in large-scale production brings opportunities to investigate the implications of their remarkable properties, which facilitates tremendous technological benefits. hBN possesses astounding chemical inertness and thermal stability up to a very high temperature. BNNTs are structurally similar to carbon nanotubes (CNT). Various fabrication processes have been adopted to develop 2D hBN and BNNTs such as ball milling, arc discharge, substitution, laser-based method, chemical vapor deposition, metal organic chemical vapor deposition, and electron beam in situ deposition. Two-dimensional hBN/BNNTs are characterized through various characterization tools like X-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy. Mechanical properties of 2D hBN/BNNTs are mostly investigated through nanoindentation experiments. Moreover, radiation-shielding measurements are performed by the tools of neutron radiation exposure.
